…lease-5.8) (#8420)

### **User description**
## Problem / Task
Backport PR #8409 to release branch `release-5.8`.
The smoke tests are failing because they rely on the public
`httpbin.org` service, which was down. We need to remove the public
`httpbin.org` dependency from smoke tests by adding a local mock service
to `docker-compose.yml`.

## Changes
- Added `httpbin.org` service using `kennethreitz/httpbin` image to
`ci/smoke-tests/plugin-aliasing/docker-compose.yml`. This allows
Docker's internal DNS to intercept requests to `httpbin.org` and route
them to the local container, avoiding reliance on the public internet.

## Testing
- Verified that the `httpbin.org` service is added to the
`docker-compose.yml` file.
- Other tests in `ci/tests/` already use this pattern successfully.
